Application filed June 5, 1913. Serial No. 771,799.

TouZZ whom it may concern Be it known that T, WALTER S. ADAMs, a citizen of the United States, and a resident of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Car-Trucks, of which the following is a specification.

The object of my invention is to provide a'suitable truck for storage battery cars, which truck will be light, durable, ellicient and satisfactory under all the conditions of service. This object is accomplished by my invention, one embodiment of which is hereinafter set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which:

Figure 1 is a side elevation of a portion of my improved truck. Fig.2 is an inverted plan view of a spring cap. Fig. 3 is a sectional view, taken on the line 33 of Fig. 2, looking in the direction of the arrows. Fig. 4 is a plan view of a portion of the structure shown in Fig. 1. Fig. 5 is a sectional view taken on the line 55 of Fig. 1, looking in the direction of the arrows. Fig 6 is a sectional view, taken on the line 66 of Fig. 4, looking in the direction of the arrows. Fig. 7 is a sectional view, taken on the line 77, of Fig. 1, looking in the direction of the arrows. Fig. 8 is a plan view of an axle box. Fig. 9 is partly a sectional view, taken on the line 9-9 of Fig. 8, looking in the direction of the arrows, and partly a side elevation. Fig. 10 is a sectional view, taken on the line 10-40 of Fig. 9, looking in the direction of the arrows. Figs. 11 and 12 show a bracket for a spring post with a seat for a spring, the bracket being used to hold the lower end of the post, Fig. 12 being taken on the line- 1212 of Fig. 11, looking in the direction of the arrows. Figs. 13 and 14 show a bracket for supporting a car body from one end to the elliptical spring, Fig. 14 being taken on the line 1414 of Fig. 13, looking in the direction of the arrows. Fig. 15 is a sectional view taken on the line 1515 of Fig. 8, looking in the direction of the arrows.

Throughout the various views of the drawings, similar reference characters designate similar parts.

The invention herein disclosed may be applied to a truck 1 which may be either connected directly to a car body, where extreme lightness is desired, or to top chords, not shown, which may be attached to a car body. In either case this truck 1 is provided with the usual wheels 2, axle 3, brake mechanism 4 and electric motor supports 5 all of which may be of the conventional form. The axles 3 are journaled in axle boxes 6 which have novel features. These axles 3 bear directly on suitable roller or other bearings, not shown, which may be of the conventional form. These bearings are secured to the axle boxes 6 by means of bolts or cap-screws which pass into suitable perforations, 7, which are located in the usual manner.

The axle boxes 6 have suitable side webs 8 and 9 united by a crossing 10 and

spring seats

11, 12, 13 and 14, the spring seat 11 be ing for a semi-elliptic spring and located at one end of the webs 8 and 9. The

spring seats

12 and 13 are located symmetrically on each side of the crossing 10 and the spring seat 14 is located at the other end of the webs 8 and 9 and is suitable for coiled spring. 7

The

spring seats

12 and 13 each carry suitable coiled springs 15, (see Fig. 5,) which is surmounted by a suitable cap 16 from which hangs a suitable bolt or spring post 17, which passes through a suitable perforation in the

seat

12 or 13 and also through a coiled spring 18 between the

seat

12 or 13 and a seat 19 on a clamp 19 and between this clamp and a tie-bar 20, the

clamp and tie-bar being held together by.

means of suitable bolts 21. By means of the nut 22 at the lower end of the spring post 17 the springs 15 and 18 are put under suitable tension so that the axle box 6 will ride sub stantially true at all times regardless of the difference in action between'leaf and coiled springs on the application of the brakes. The tie-bar 20 unites the two axles 6 on the same side of the truck. This tie bar 20, in conjunction with the posts 17 and springs 18 serves to prevent tilting of the axle box under the normal conditions of service. This tie bar constitutes'an equalizing bar.

The spring seat 14 carries a suitable coiled spring 23, is surmounted by a suitable cap 24, and this cap rests against a top chord or the car body and is secured to one or the other, according to which structure is used.

In the structure shown this cap is secured to the car body. This cap 24 is provided with a suitable cup 25 and central perforation 26 so asto receive a suitable spring post '27 which passes therethrough, and also the-conventional manner, that is the band 30 of this spring rests on said seat and suitable U bolts -31 secure the spring '29 in place. Ihe free ends of the spring'29 carry suitable seats 32 in which rest swing links 33 which also engage suitable brackets 34: which are connected, as shown, or otherwise, as desired, so that the car body is carried by the caps 24 andth'e brackets 34 and is always spring supported while so carried in a manner which permits a limited transverse or vertical movement. The parts are preferably shaped as shown in Fig. 7, so as to facilitate this result.

Below the seat 11 and fixed to the axle box 6 by suitable bolts 35 is secured the crossing 36 from which are carried both the brake rigging 4 and the motor support 5.

. When a truck frame is made as above set forth the batteries may be carried by the tiebar 20 or otherwise, as desired. The bars may also carry the motor should such a construction be desired; In any event, when the truck is in use and the car is loaded so that the

springs

23 and 29 are compressed the axle '3 can shift to a slight extent as above stated because of the flexible connections of the springs to the car' body. It is also true that the axle boxes 6 will be held in proper relation and in their normal condition with- V out regard to the difference in action between the

springs

23 and 29 because of the tension on the springs 15 and 18 as above set forth.
